TikTok Car Cleaning Hacks: Ones That Work, and Ones You Should Skip
Say it with me, everyone: don’t believe everything you see on TikTok.
If you’re like most people, you think TikTok is a valuable resource. I’ve learned valuable things from child psychologists (that I’ve verified through independent research) about toddler behavior. I’ve learned about fitness and dieting from dieticians and fitness trainers while doom scrolling, and recently, I’ve spotted car cleaning “hacks” that have me raising eyebrows.
I’ve been detailing my cars since I was a teenager. I take great pride in washing, polishing, and waxing my cars twice a year. I enjoy detailing my interior and collecting car care products in my garage (there was a point where my husband told me to stop buying them…). This is all to say, I know a thing or two about maintaining a car’s paint.
So, when I see people promoting car cleaning “hacks” like using baking soda and vinegar to clean stains off of fabric seats, or dumping a can of Coke onto foggy headlights, only for the video to cut and show brand new, shiny headlights, it irks me to my core. To save you the trouble, I’ve reviewed six popular hacks, did the research, and then I’ll tell you why they would or wouldn’t work.
This story is 100% human-researched and written based on actual first-person knowledge, extensive experience and expertise on the subject of cars and trucks.
Can A “Magic Eraser” Give Leather and Plastic a Matte Finish? Yes. But Err On the Side of Caution.
This one is super interesting from a scientific standpoint. When I first saw someone wiping a Mr. Klean Magic Eraser on a leather steering wheel, and then, almost by magic (see what I did there?), the leather had a beautiful, soft matte finish. But it’s not just a clever “hack” for a leather-wrapped steering wheel. On plastic door panels, like the ones on my old Subaru, TikTok claims I can use them to remove stains and essentially resurface them, to make them look new. It does work like a magic wand, lifting years of dirt and oil from the surface in a single swipe. Even Mr. Clean’s website lists a car’s interior as part of its “100+ messes” webpage.
But science says, “Beware.” Melamine foam, which is what a Magic Eraser is composed of and where its cleansing magic comes from, is actually an ultra-fine abrasive. It has the microscopic grit of roughly 3000-to-5000-grit sandpaper. It “cleans” by physically shaving off a microscopic layer of the material, sort of like the relationship between paint polish and clear coat. On leather, it strips the factory’s clear protective coat, which will cause the leather to dry out, crack, or lose its color very quickly.
So, this will work very well on the plastic door panels. However, when it comes to leather, proceed with caution. If you’re going to use it on leather, be sure to follow up with a leather conditioner or treatment to protect it.
Will a Dryer Sheet Remove Bug Carcasses or Tar from Your Car’s Paint? Yes! But Only If You Do It Right
This one was a fun one to watch. In a video, a young man took a dryer sheet, like the Bounce ones I use, and used it like a magic eraser on tar that had collected on his fenders and wheel wells when driving near a construction zone. In just a few, minimal effort swipes, the tar was gone. He claimed it would work on dried, dead bugs, too.
The good news is, if you have them handy, yes, it will work fantastically, thanks to a few chemical additions. Dryer sheets are coated in aliphatic alcohols and softening agents (these are what make your clothes softer, after all) that do a great job softening organic bug matter, or tar. However, the sheet itself is made of polyester fibers that can act like fine steel wool on your car’s paint. Depending on how hard you scrub, it can leave thousands of tiny swirl marks and micro-scratches in your clear coat.
Which isn’t a big deal if you’re a nerd like me and have a polisher handy, and already plan to give the car a solid polish. But if you’re not, then you can leave a mark on your paint that could be more noticeable than tar or dead bugs. So, be extra careful not to apply your full strength on this one.
Can Baking Soda and Vinegar Lift Stains from Your Carpet? No.
Watching these cracked me up a bit, because it brought me back to elementary school science class, where we made clay volcanoes and used baking soda and vinegar as makeshift magma. It looked cool and smelled terrible, but I didn’t remember the brown coming off the clay.
If you need a refresher, baking soda (a base) and vinegar (an acid) neutralize each other when mixed, creating water, a little salt, and carbon dioxide gas (the bubbles). While the bubbling can physically help loosen loose dirt particles, which makes it look like it’s removing a stain, you are mostly just left with wet, salty water trapped in your car carpet, which can cause mildew if not vacuumed out with a shop vac.
So, does it work? No. But it looks like it works. For really stubborn stains, I typically use a dedicated carpet cleaner with a plastic brush attached, let it soak, and then vacuum it up with my carpet cleaner. Works every time.
Will a Cheap Squeegee Remove Your Dog’s Hair With Minimal Effort? Yes!
This was one of the first ones I saw that made me confident it was a winner. A TikToker used a cheap, Dollar Store window squeegee, dragged it across their cargo area, cloth seats, or fabric floor protectors with minimal pressure, and looked amazed as stubborn dog hair was immediately removed. And thankfully, the success behind this one is easy to explain.
The rubber creates static electricity and friction that pulls the embedded hair out of the fabric weave. Easy. It’s entirely mechanical, uses zero chemicals, and is totally safe for the interior carpets, so if you have a hairy dog, I’d even suggest keeping one in the car or in your bucket of car cleaning products for future use. It’ll save you a ton of time, and you won’t need the vacuum. Though you should still vacuum it to get rid of the dirt and dander.
Does WD-40 Make Scuffs and Scratches Disappear? No—Don’t Let Me Catch You Falling For These Kinds of Car Cleaning Hacks
This was a cringey one, and I don’t blame a lot of people for falling for this one, because I personally know a lot of car people who treat WD-40 like it’s a compound that fell from Heaven. It can shush a squeaking door, it can loosen even the most stubborn of seized bolts, and according to TikTok, it can remove scuffs and scratches from your car’s bumper, door panels, or other painted surfaces. I watched a woman spray WD-40 on a scuffed bumper and then essentially wipe it away. One of the easier car cleaning hacks I spotted.
And there is some cool science behind that, but it’s not good science. You see, WD-40 is a petroleum-based lubricant. Not a cleaner. So, it’ll fill in the microscopic grooves of the scratch, which changes how light reflects off it; temporarily hiding it. But WD-40 doesn’t dry—it evaporates and washes away the next time it rains, or you wash the car, revealing the scratch again. Plus, petroleum distillates can soften certain plastics or rubber trim if left to sit, which can cause more damage. So, skip this one.
The best thing to do for a scuff or scrape, if it’s a light scratch, is to polish it.
Will Toothpaste Refresh a Foggy, Yellow Headlight? Yes, But Not for Long
This was an interesting one, too. The instructional video I saw made it look easy: You smear a standard, non-gel white toothpaste onto a hazy, yellowed headlight, scrub it vigorously with a microfiber towel or an old toothbrush, and rinse it off. The result is a minty-fresh headlight that looks like it came from a car sitting on a dealership’s showroom floor. And you’ll get the result you’re looking for—but first, you should know how toothpaste works.
If you didn’t know, toothpaste works so well because it’s a polish. And, by now, you understand that polish contains mild abrasives that are used to scrub away small scratches by shaving off microscopic layers at a time until the scratch is gone. Toothpaste does the same for your teeth. Your teeth aren’t yellow because the abrasives in the paste remove icky stuff from a tooth’s enamel.
Therefore, because toothpaste is a mild abrasive, it physically grinds away that micro-layer of dead, oxidized plastic that was damaged by the sun’s UV rays and heat cycles, revealing the smoother, clearer plastic underneath. The gratification is instant and with minimal effort, but there’s a catch. While toothpaste removes the damage, it also removes the factory UV protective clear coat that was originally sprayed onto the lens. Once that factory UV barrier is gone, the bare polycarbonate plastic is completely defenseless against the sun.
I polish my own headlights, but I follow up with a UV protectant spray to help keep them from oxidizing so quickly. If you want to go hardcore on protection, there are ceramic clearcoat kids that protect your headlights post-polish for years. So, the toothpaste will work on the cheap, and in an instant. But you should look into adding a UV protectant, too, unless you’re okay with using your toothpaste every couple of months.
My Key Takeaway Was This: Stop Looking For Easy Ways Out
Seriously. Just stick with what we know works. For instance, I wash, polish, and wax my cars (yes, all four of them) twice a year. Once before the height of summer, and then again before winter strikes. I treat the windows with a hydrophobic spray so a surprise rain storm won’t reduce my visibility and I use Back to Black on all my exterior trims and plastics to protect them from fading.
Doing all this makes it so I don’t have to resort to “hacks” to keep my car looking nice. Like anything else, sage advice and experience beat out quick tricks every time.
